Ditto. Back then my parent often locked the room with the computer so that I could 'focus' on my study instead. And this guide helped my learning about pascal, C and then x86 assembly (when my father got so frustrated he took out the HDD and I have to run MenuetOS instead). I think the section about Zen and Analytic thinking helps shaped my way of thinking. Before that I just charged blindly into problems, only to get stuck somewhere. But after reading the guide, I often stop for a while, thinking 'why doesn't this work?' and try to figure out how, back gathering all the evidences and make a mental model of it in my brain. Interestingly it is quite useful for programming too.
